This invention relates to a speaking clock, the general object of the invention being to provide a phonographic attachment for the clock which will call out the hours and half-hours in place of the clock striking the hours so that it is not necessary for one to stop and count the strikes in order todetermine the hour being struck.

Another object of the invention is to provide means for resetting the reproducer of the record after the end of the record has been reached by the needle so that the machine will start over again.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in theaccompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying draw- -ings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a perspective View of the improved clock.

Figure 8 is a view showing how the movement. of the turntable of the phonograph 1s controlled by the clock mechanism;

Figure 9 is a view of the stop lever of such means.

Figure 10 is a bottom plan view of the turntable.

Figure 11 is an edge View of the same.

Figure 12 is a face View of portion of the record used with the device.

In these views, 1 indicates the casing of the clock and 2 indicates the casing of the phonographic arrangement which forms a base for the casing 1. The clock may be made of the usual or any desired construction, andbs in carrying out my invention I cut off the arm 3 of the alarm releasing means, as such alarm means are not used. This arm 3 is connected by a link with a lever 5 which is pivoted to a bracket 6 connected with the inner wall of the casing 2 so that the said lever will be rocked by the movement of the arm 3. A spring 7 tends to hold the lever 5 with its upwardly extending outer end against the bottom of the turntable 8. of the grapho phone which is arranged in the casing 2. This table 8 has an arc-shaped strip 9 connected to its bottom in such a manner that the projecting part of the lever 5 will first pass over which will tend to check the movement of the turntable and the tapered part of the'strip,

then the lever will engage a depending part 10 of the member 9 and thus further movement of the turntable will be prevented until the lever has been movedto release the table; The record 11 has its reproduction grooves 12 so formed that the outermost groove 12 will reproduce the words One oclock, the next groove will reproduce the words One thirty or Half past one, the next groove will re-' produce the words Two oclock and so on to the end of the record, the end groove reproducing the words Twelve thirty. As

shown in Figure 12, plain grooves are formed. 1n the record before each reproducing groove so that the turntable can make several revolutions before the needle of the reproducer 13 will strike the reproducing groove; This will enable the turntable to reach its full speed before the needle strikes the reproducing groove. The spindle of the turntable is provided with a key for engaging a keyway 14 in the table and a keyway 15 in the record and the upper end of the spindle is threaded to receive a nut 16 so that the turntable and record are held on the spindle by the nut. By using the key and the keyways, there is no danger of the record being misplaced on the table and it must be properly placed on the table when being put thereon sothat the 100 reproducing grooves will be in a proper position relative to the operation of the brake by the clock mechanism.

In order to bring the reproducer arm back 5 to its starting point after the needle has passed over the record and at the end of twelve hours, I place a roller 17 in the reproducer arm 18 and place a track forming strip 19 under the roller, one end of this stripbeing pivoted to a bracket 20 connected with the phonographic casing and its other end being slotted, as at 21, to engage an eccentric pin 22 on a disk 23 which is fastened to a shaft 24 of a spring motor 25., The disk 23 has a projection 26 thereon which is adapted to be engaged by a spring latch 27, the spring of which is shown at 28 and this spring latch has an arm 29 dependingtherefrom which is adapted to be struck by the reproducer arm at the end of the record so that the said reproduoer arm will swing the latch intoinoperative position, thus releasing the disk 23 I and permitting it to be rotated by the spring motor through means of the shaft 24:. This will cause the eccentric pin to move the track forming strip 19 upwardly into a tilted position where it will engage the roller 17 thus moving the reproducer arm upwardly so as to move the needle of the reproducer off the record. As the track forming strip is in a tilted position, the weight of the reprodueer arm and its attached parts will cause the arm and roller 17 to run down the track forming strip 19 until the arm strikes the stop 30 on the said strip, which stops the arm w1th the needle at the beginning of the record. At this time, the'disk 23 will have made a complete revolution so that the track forming strip will be lowered. again so that the needle can engage the first groove in the record and further movement of the disk will be prevented by the latch 27 engaging the stop 26. Thus each time the needle reaches the end of the record, the parts will be returned to their starting position. v

The motor 25 has its spring 25 wound by the turning of a shaft 31 by a key introduced through a hole 32 in the casing,-the sald shaft entering the motor casing and having the spring 25' attached to its inner end. The other end is attached to the casing of the drum 25 which is connected with the shaft 24. Ratchet mechanism 32 is associated with the shaft 31. I also provide governor means 33v for the motor 25, as shown in Figure 5.

The shaft for the motor 34;- of the graphophone, shown at 36, passes through the easing 2 so that it can be wound by a key.

7 The reproducer arm is connected to a secthat the arm can rock about a horizontal axis to enable it to be lifted at the end of thereo- 0rd and returned to its starting position. The section .37 is rotatably mounted in a tion 36 by the universal oint 37 which is pivotally connected together by the pin 38 so be moved to a position where it will release the turn-table of the graphophone so that the table will be rotated by its motor and thus cause the needle to en age a reproduction groove so that the grapIiophone will announce the hour and half-hour. Of course, if desired, the graphophone could announce the quarter hours. VVhenthe arm 3 drops, due to the movement of the clock mechanism, the stop lever5 willbe moved back to its operat-ive position and thus stopthe turn-table.

This will continue until the needle reaches the.

end ofthe record, when thereproducer arm,

striking the depending part 29, will move the latch 27 to inoperative position so that the disk 23 will be rotated by its spring motor to raise the track part 19 to cause the reproducer. arm to move back to its starting position. This movement will takev place every. twelve hours, as will be understood. It will be seen that the only thing necessary to keep the phonographic announcer inoperation'is 0 5.95 wind the springsof the motors 25 and 34. Of course, a new recordwill have to be put inplace after the old; one has become worn and the needle will have to be renewed from time to time. I I

It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and lIItht1G5 combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

. What I claim is: I v

A stop mechanism for a phonograph turnc io table, includinga stop lever for controlling the rotary, movementof the table, and an arc- }shaped rib on the bottom of the turn table for engaging one end of the lever, said rib gradually lncreaslng 1n thickness .from its 25115 forward to its rear end, and a depending part .on the rear end of the. rib, whereby the engagement of the lever by the rib will check the movement of the turn tablc, and the engagement of the depending part with the latc12 ter will stop the turn table. i

vIn testimony whereof I affix my signature.
